Terminal Paging with Fast Speed , Low Cost and High Quality of Service 3 Table 1

Dynamic location management for a mobile terminal is a key problem in wireless communication networks. There are three fundamental performance and cost issues in terminal paging. The first issue is the speed (i.e., time delay) of terminal paging. The second issue is the cost (i.e., the number of cells paged) of terminal paging. The third issue is the quality of service (QoS), i.e., the probability that a mobile terminal is found. It is clear that it is hard and a challenge to achieve fast paging speed, low paging cost, and high QoS simultaneously. The motivation of this chapter is to show that it is possible to achieve fast paging speed, low paging cost, and high QoS simultaneously. We propose the method of aggressive paging, which essentially is to page an area smaller than the paging area, and to have the fastest speed (i.e, the shortest time delay), low cost, and high QoS. Such simultaneous achievement of high performance and low cost are obtained based on our knowledge of the location distribution of a mobile terminal in a paging area. To the best of the author’s knowledge, such a paging method has not been reported in the existing literature. ∗E-mail address: [email protected]. 2 Keqin Li
